Don,
Yes, Anderson Powerpoles are fine connectors. Just don't use too many
of then when powering a 100 watt rig.
IMHO, Rigrunners are handy things, but running a 100 watt transceiver
from them is cause for significant voltage drops. Each contact point
will have some resistance. A fused Rigrunner has 6 contact points in
line with the power supply (you need to count those in both the negative
and positive lines)
If you have a K2/10, you can run it from the Rigrunner, but if a K2/100,
wire it direct to the power supply - there will be less voltage drop.
Save the Rigrunner for accessories and other lower current devices.

Bob,
Is it safe to run my K2 using Anderson Power Pole connections, and/or RigRunner
equipment?
For my info, what is the reason for NOT using them?
I’m rewiring, and I want to do it right!

Nuts, just measure the drop between radio and power supply see if it is
reasonable. Mine is 0.25 volts when transmitting. I run 14.0 out of supply.

As to the RigRunner power pole strip.........PUT IT IN THE TRASH where it
belongs. NEVER NEVER NEVER use a power distribution strip to power a 100
watt radio. ALWAYS connect the radio direct to the power supply terminals.
NO exceptions!

After more checking, I suspect the internal 100W amp is the common factor
in the poor keying characteristics I'm seeing and hearing about from my
rig. I am trying to determine if my power supply is doing it's job.
I'm using a TenTec 963 switching supply rated at 25A continuous. At rest
the K3S panel display shows 13.6V, with full power key down it dips to 11.5
or so. This seems like a lot. I'm running the power cable thru a
RigRunner Powerpole strip. If I can dig out another power supply from the
packed boxes I can wire the K3S directly to the supply.
Is 11.5V at key down enough to cause the slow rise time being reported?
